COMBINED MOP AND WRINGER.

Specification of Letters Patent.

Patented Mar. 13,1917.

Application filed August 2, 1915. Serial No. 43,133.

To all whom it may concern: I 3

Be it known that I, IVILLIAM J. BAUER, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Combined Mops and \Vringers, of which the following is a specification.

My invention relates to a combined mop and wringer, the principal object of which is to provide a device that will serve as an.

efficient mop and which may be easily manipulated to thoroughly wring the mop without the hands of the operator coming in contact with the mop. Further advantages of the invention reside in the operating mechanism for imparting a rotary movement to one of the mop holding members whereby the initial twisting of the mop is effected at a comparatively rapid rate and the final twisting or squeezing is accomplished by a slower and more powerful twisting movement. Still a further object of the invention is in providing such a device with suitable' means for exerting pressure upon the top" surface of the mop to better hold it to its work.

Having now described the nature and general objects of the invention I will proceed with a more detailed description of the parts and their operation as shown in the accompanying drawings, in which Figure 1 is a side elevational view of my improved mop in operating position, with the handle broken away.

Fig. 2 is a plan view ofFig. 1.

Fig. 3 is an enlarged detailed section of the operating mechanism for imparting rotary motion to one of the mop holding members.

Fig. 4: is a section on the line 4-4 of Fig. 1.

Fig. 5 is a perspective view of one of the mop holding members.

Fig. 6 is a plan view of the two mop holding members showing a slight modification thereof.

Referring now more particularly to the drawing,-the structure comprises-a handle 7 having a metal frame attached thereto at its lower end and constituting a part of the handle. This metal frame consists of two parallel... members 8 and 9, suitably spaced apart, and integrally connected at their lower ends by an end piece 10. The end piece is provided with an opening 11. Near the upper ends of the end pieces 8 and 9 are two webs 12 and 13, each provided withopenings 1%. The handle 7 extends between the free ends of the frame and is secured thereto in any suitable manner such as by the screws 15. A spiral shaft16 is positioned between the members 8 and 9 and extends through the opening 11 at one end and through the opening let at the other end, the webs 12 and 13 and end piece 10 forming bearings therefor. A washer 17 is mounted upon the upper end of the shaft .16 and is held in place by a cotter pin 18, thus preventing the shaft froni slipping from its bearings. Slidably mounted upon the frame members 8 and 9 is a sleeve 19 that is longitudinally movable relative tothe frame, but non-rotatable with respect thereto. The shaft 16 is in spiral form, preferably constructed by twisting a rectangularly shaped bar, and it is to be particularly noted that the pitch of the convolutions of the shaft 16 gradually decrease in their angles from the bottom of the shaft'toward its upper end where it entersthe openings 14. The purpose of graduating the pitch of the convolutions will be hereinafter more fully explained.

Connected to or formed integral with the collar 19 is a nut 20. This nut has a rec tangular opening 21 to receive the rectangularly shaped shaft 16. It will be readily seen from the foregoing that by sliding the collar 19 upon the frame members 8 and 9 a rotary movement will be imparted to the shaft 16. Fixed to the lower end of the shaft 16 is a metal loop 22, which loop may be either continuous or have a portion cut away as shown at 23 to permit of the mop 24 being attached to the loop without the necessity of cutting the mop and then passing one end'through the loop, after which the two ends of the mop are secured together.

Projecting from the lower end of the frame members is anarched support 25 thatis provided with a suitable opening near its free end'for pivotal attachment with a part of the device hereinafter to be described. The free end of the arch support 25 terminates in a stop 26 offset at a slight angle to the angle of thearch immediately above the pivot point. The non-rotatable mop holding member 27 is so formed as to provide a loop at its outer end with a plurality of teeth 28 upon the upper surface of one side of the loop; the teeth preventing the mop from slipping. A presser member 29 is in the form of two parallel bars which are secured to the mop holding member 27 at one end and having their other ends 30 bent at substantially right angles to the main body of the bars and provided with suitable openings to receive the pivot bolt 31. Extending beyond the bolt openings in the ends 30 and inte rally connected therewith is a stop 32. The outer end of the arch support 25 extends between the ends 30 and is connected thereto by the pivot bolt 31. The stop lies beneath the arch support 25 while the stop 26 lies above the presser member 29 and is adapted to bear against the stop block 33 that is secured to the two bars of the-presser member; the stop 26 in combination with the bar 33 thereby limiting the pivotal movement of the mop holding member27 in one direction, relative to the arch support 25 and the stop 32 limiting the pivotal movement of the mop holding member 27 in the opposite direction.

The mop holding member 27 may also have a cut out portion as shown at 34: which performs the same function as the cut out portion 23 in the mop holding member 22.

The operation of the device is as follows: In the normal operation when performing the mopping function, the parts are in the position shown in Fig. 1 and the mop is moved in the same manner as any other mop. The presser foot 29 extending rearwardly from the mop holding member 27 serves to keep the mop in flattened form and by raising the handle toward the vertical position relative to the floor, the stop 26 strikes the stop block 33 and this additional pressure may be placed upon the top surface of the mop to thereby hold it better to its work. After the mop has become soiled, by lifting the same from the floor the mop holding member 27 and presser foot 29 fall downwardly until the loop ends of the two mop holding members are in substantial axial alinement with the handle, as shown diagrammatically in Fig. 1. The operator thereupon slides the collar toward the free end of the handle and the initial movement of the collar rotates the mop holding member 22 comparatively fast, due to the pitch of the spirals near the lower end of the shaft 16. As the collar approaches the upper end of the shaft, however, the angles of the ing, a handle, a shaft rotatably connected to said handle, a mop holding member connected to said shaft and adapted to rotate therewith, a sleeve slidably connected to said handle and shaft and adapted to impart a rotary movement to said shaft, a support connected to said handle, a presser member pivotally connected to said support, a mop holding member connected to said presser member and means for limiting the movement of said presser member relative to said support.

2. A combined mop and wringer comprising a handle, a shaft rotatably connected to said handle, a mop holding member connected to said shaft and adapted to rotate therewith, means slidably connected tosaid handle and shaft and adapted to impart a rotary movement to said shaft, means for varying the rotary movement of said shaft and a second mop holding member pivotally connected to said handle.

3. A combined mop and wringer comprise ing a handle, a spiral shaft rotatably connected to said handle, a mop-holding member connected to said shaft and adapted to rotate therewith, a sleeve surrounding and slidably connected to said handle and shaft and adapted to impart a rotary movement to said shaft, an arch shaped support connected to said handle, a presser member pivotally connected to said support and having a loop formed at its outer end to receive a mop, means on said loop for preventing the mop from slipping and means for limiting the pivotal movement of saidpresser member relative to said archshaped support.
